NAS-IR
Nasal Rinse
Isotonic solution

CE 0476 medical device for nasal irrigation, indicated for daily hygiene through the showering of the nasal mucous membranes, in order to prevent obstructions due to the stagnation of phlegm secretions or for those who suffer from respiratory difficulties due to pathologies such as: common cold, cough, sinusitis, post-operative recovery, otitis, asthma, bronchitis, nasal polyps, allergens or caused by environmental contamination such as dust, smoke or fumes. Adjuvant in the treatment of nocturnal nasal obstruction.

Intended use
The device allows sterile and pyrogen-free (isotonic) physiological solution contained in 250 or 500 ml bags to flow by gravity or manual pressure into the nasal cavities (upper airways). This device has an irrigation nozzle at one end that directs the jet of physiological solution towards the meatus of the nasal cavities, exerting a powerful cleaning action in the cavities themselves and in the nasopharynx, promoting the removal of all secretions, dust, allergens, and chemical substances that may be present.

Dosage
For adults and children (over 3 years) 1 to 2 irrigations per day are recommended or according to different medical specifications.

Instructions for use
• Carefully remove the first protective bag of the pouch.
• Warm the pouch with the solution to about 30-35°C by immersing it in hot water. Then unscrew and remove the protective cap.
• Fix the suction cup to a smooth surface above the sink.
• Open the package containing the device.
• Lower the roller wheel until the tube is completely closed.
• Remove the cap and firmly screw on the male connector of the device. Holding the connector between your fingers, break the cone (arrowhead part) with the other hand to activate the bag-device connection.
• Hang the bag on the suction cup, fixing it appropriately.
• Tilt your head forward over the sink, in a position lower than your shoulders.
• Bring the irrigation nozzle to your nose and gently press on the nostril. Breathe through your mouth throughout the treatment.
